Solenoid valve troubleshooting: the most common failure modes

Figure 1: 2/2-way solenoid valve
Solenoid valves are common components in pneumatic and hydraulic systems, controlling fluid and gas flow. While relatively simple, they can encounter issues like not opening/closing properly, leaking, or overheating. Another common issue is a too low differential pressure for indirect operated solenoid valves.These issues often stem from debris, damaged parts, or electrical problems. Fixes include cleaning, replacing damaged components, and repairing electrical or cooling systems. These failure modes apply to all kinds of valves, such as 2 way and 3 way valves.
